Abstract: PROBLEM TO BE SOLVED: To provide a color image processing method that reduces reverse taking and sight through while preventing an input image from being excessively smoothed. SOLUTION: First a difference between a set-off reduction output image and a smoothed input image being a cause to the output image is calculate with respect to a target pixel (step S12). Then in a step S13, pixel values in the difference image is decided in advance and pixels whose value is greater than a threshold TH1 with correlation to a paper transmittance are regarded to be an error in the set-off reduction processing and the pixel value of the input image is outputted as it is (step S18). In a step S14, the intensity of edges is calculated for the pixels whose value is the threshold TH1 or below, the pixels whose intensity exceeds a threshold TH2 are regarded to be part of an image of a front side of the original and the pixel value of the input image is outputted as it is (step S18). A difference between the original image before smoothing and a non-front side component is taken from the pixels whose intensity is the threshold TH2 or below and outputted (step S15). The processing above is applied to all pixels.
